---* Set attribute values to name.<br>
---* param name Specifies the attribute name.<br>
---* param index Specifies the index of the generic vertex attribute to be modified.<br>
---* param format Specifies how the vertex attribute data is laid out in memory.<br>
---* param offset Specifies the byte offset to the first component of the first generic vertex attribute.<br>
---* param needToBeNormallized Specifies whether fixed-point data values should be normalized (true) or converted directly as fixed-point values (false) when they are accessed.
